One of the objects of my invention is to provide an interchangeable threadless hose coupling designed, primarily, for a quick and effective method of coupling and uncoupling Shose with a smooth joint which permits ofy lengthwise pulling or dragging of the hose through grass, brush, timber and the like without the danger of the coupling becoming snagged.

10. Another object of my invention is to increase the internal area at the uncture of the coupling, decrease metal, and still retain perfect o-utside cylindrical form with no proj ections, and maintain a uniform sealing surface all around the joint.

Another object of my invention is to eliminate the necessity of separate male and female joint members.

nother object of my invention is to pro- 0 Vide. means for quickly breaking ther joint Without the necessity of striking the couplingn thus eliminating the possibility of battering the coupling to the point of injury; and with these and other objects in view my inventiony consists of the parts and combination of parts as will be hereinafter pointed out.

In the drawings:

Figure l is a side elevation of my improved coupling. Y

Figure 2 is a View illustrating the tivo sections of the coupling in position ready to be assembled.

Figure 3 is a top plan View of the coupling member.

My improved coupling comprises two members of identical construction-and, therefore,

a description of one is all that is necessary in order to practice the invention.

The coupling member 5 is of cylindrical tension 6 over which the end of a. hose lis securely fastened. This member is provided with an oblong Waterway 7 to increase internal area at the j unctureof the two members. By making the waterway oblong I am enabled to decrease the metal in the member and still retain the outside cylindrical form` free from projections, and also provide. and maintain an increased uniformsealing surface 8. It will be appreciated that by'makshape and is provided with the reduced eX`` the waterway oblong disposing` the l i sealing surface i8 .oblique to c the longitudinal axis o-fthe couplingI secure a materially increased surface as compared with a sealing surface at right angles to the longitudinal axis of the member.

In the side walls of the sealing surface 8 I provide a groove 9 disposed at an angle diverging from said surface, said groove opening at oneend through the face of the mem- 6a ber as clearly shown in Figure l. At the other end of the'groove 8 I provide a locking, or clamping dog 10 (two to each member) which extends outwardly at right angles to the groove and terminates beyond. the sealing face 8,and is provided with a groove 11, the upper wall 12 of which overhangs the sealing surface 8 and converges toward the surface 8 from the axis of the member toward its perimeter thereby forming a wedge shaped groove, the rib 13 of the locking dog of one member being adapted to enter the groove 9 of the other member andtheside wall l4'of the. sealing surface of one membery being adapted to slide inthe groove ll in the dog l0 ofthe other member.

, The locking dogs l0 do not abut with each other when the joint is sealed, but are spaced from each other as indicated at l5 into which space an unlocking member 16 may be in- B0 serted to move the joint members 5 away from each other whereupon they may easily be separated by hand to uncouple the Yhose lengths. n

What I claim is: 85V

In a hose couplinof having two identical in terchangeable members having cooperating bearing faces each having a side edge face disposed in spaced relation to the adjacent sides of the member and terminating short of 90 one end ofthe bearing face,-grooves in the said side faces of the member opening at their rear ends through the surface ofthe bodyl f and lying lbeneath saidbearing face mainly in r rear ofthe transverse center thereof and eX- f tending forwardly inl diverging relation to said face, Wedge-shaped tongues being'thereV by formed between saidbearing face andY said grooves, locking dogs'at the sides of the member between the said side'faces and front ,10S

Cil

end ofthe bearing and extending at right angles thereto above thebearing face and having shoulders at their inner ends, and a groove formed longitudinally in the inner side face of each locking dog, the upper walls of said grooves being arranged to overhang the bearing face and extending rearwardly at a diverging angle to said bearing face reverse to that of the iirstnamed grooves, the length of the dogs being slightly less than the distance between the shoulders and rear end of the bearing face whereby when the meinbers are coupled space will be provided be-4 tween faeing shoulders for insertion of a 'ltool for facilitating separation of the memers. v

In testimony whereof I aiiix my signature. Y ELTON F. ROSS.
